ODELON 1). WILSON, OF GREENVILLE, SOUTH CAROLINA.

MITER-BOX.

Application filed December 23, 1914.

To all whom it may concern:

Be it known that I, ()DELoN D. WILSON, a citizen of the United States, residing at Greenville, in the county of Greenville and State of South Carolina, have invented certain new and useful Improvements in Miter- Boxes, of which the following is a specification.

This invention relates to miter boxes, and is particularly concerned with the provision of a box which shall rotatably support the saw through a horizontal angle of 90 in enabling variably angled cuts to be made upon the work.

As a principal object, this invention contemplates the provision of a miter box including a supporting table for the work, means rotatably mounting the saw in horizontal relation to such work and catch means maintaining any particular angled relation between said saw and said work.

A further object is to provide a miter box of the type set forth including vertically movable guides for the saw coacting with fixed guides mounted upon a rotatable arm so as to permit the saw to be operated in a vertically true manner upon the chosen horizontal angle.

A still further object is to provide means carried laterally of the miter boX and transversely adjustable to support work in the desired position upon the miter table and to also provide gage means to be carried by each vertical guide for determining the depth of a out.

An object of equal importance with the foregoing is to construct a miter box having the above enumerated novel advantages with such regard to proportion, number and arrangement of parts as to render the same capable of being -cheaply manufactured as well as durable and efiicient in operation.

The above and additional objects which will become apparent as this explanatory description proceeds, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

with reference to the drawings, wherein there is illustrated the preferred embodiment of this invention as it is reduced to practice and throughout the several views Specification of Letters Patent.

Patented Feb. 6, 12M. Serial No. 878,777.

of which like characters of nate similar parts:

Figure 1 is a front elevation of the miter box comprehended by this invention,

Fig. 2 is a plan view of the matter disclosed in Fig. 1,

Fig. 3 is a transverse line 33 of Fig. 2,

Fig. 4 is a perspective view showing in de tail one of the vertical guides as removed from the box, and

Fig. 5 is a fragmentary longitudinal section taken through one of the transversely adjustable lateral work holders.

In the embodiment of this invention to be disclosed, there is provided a miter table including the top-10 of an oblong shape adapted to be supported by leg pieces 11 secured at the extremities thereof as particularly shown in Figs. 1 and 2. A back piece 12 is provided for this table top 10 and is formed with the vertical corrugations 13 illustrated against which the work is adapted to rest and which is accordingly adapted to prevent the undue slipping of such work longitudinally of the table. Formed in the table top is the triangular recess let which is sunk reference desigsectional view on the approximately one-half into the top 10 and has its sides perpendicular to each other and making angles of 45 respectively with the transverse center line of the table. At the intersection of this mentioned center line with the back 12, the latter is vertically cut away or slotted to allow for the interposition therein of a saw 15 as shown in Fig. 3, in the manner to be more clearly hereinafter described.

Upon the underside of the table top 10 there is secured a latch panel 16 which projects in the arcuate manner illustrated beyond the forward edge of the table top and radially with respect to the angled sides of the groove 14:, such panel extending longi tudinally the entire length of the table between the leg pieces 11. Similarly positioned but at the rear under edge of the top 10 is a strip 17 which is formed with an arcuate integral boss 18 adapted to accommodate therein the pivoting screw 19 for the swinging saw guide lever 20 which is secured against the strip 17 by means of a suitable nut 21 carried on this mentioned pivoting screw. Forwardly and spaced vertically below the panel 16 a sufficient distance to accommodate the lever 20 therebetween is an arcuate guide strip 22 serving to support the lever during the latters rotation, spacing blocks 23 securing this guide to the undersurface of the table at its rearward extremities.

Circumferentially alined with respect to the pivoting screw 19, which may be stated to be at the intersection of the sides of the groove 1%, and formed in the undersurface of the latching panel 16 are the apertures 24 serving as keepers for a latch 25 projecting through the lever 20 and having its opposite extremity secured in a suitable strap 26 apertured at its other extremity to receive the rigid pintle 27 secured to the lever and prevented from displacement upon such pintle by means of a pin 28 transfixing the latter. Similarly mounted and abutting the strap 26 for the greater portion of its-length is the operating strap 29 also prevented from displacement upon the pintle 27 by means of the upper pin 30 and having its opposite end apertured to receive the pintle 31 upon which it is maintained by the pin 32. The expansible'coiled spring 33 is interposed between this extremity of the operating strap 29 and the rotatable lever 20, surrounding the pintle 31 for this purpose and normally maintaining the latch pin 25 in its set position with relation to one of the apertures 24 of the latch panel 16. It will be obvious that manual manipulation of the operating strap such as to compress the spring 33 will force the latch strap 26 downwardly in bringing the latch '25 out of engagement with its keeper when it is desired to freely shift the lever 20 owing tothe fulcruming effect provided by the transverse pintle pins 28 and 30.

It is upon this rotatable lever that the saw guides are to be carried, such guides including the fixed members 3% with relation to which the members 35 are vertically adjustable. Reference being had particularly to Fig. 4-, it will be seen that the members 3st comprise a substantially cylindrical central portion bored to receive the stem 36 of the slidable member and provided at the extremity of one diameter with pairs of buttress guides 37 each pair of which incloses a dove-tailed groove denoted by the numeral 38 of the figure under perusal. In these grooves are slidable properly shaped lateral guides 39 which may be secured in suitably spaced wing portions 40 of the member 35 which is similarly formed to the fixed guide as regards the central cylindrical portion and the guides or wing portions buttressed thereon. Suitable adjusting screws ll render the guides 39 adjustable in these wing portions although such guides may be formed integrally with the solid wing portions 4L2 elsewhere illustrated in this connection. It is to be seen that this arrangement of guides while readily permitting adjustability or removal. of the members 35 serve to render such movement when the saw is employed with the guides 35 absolutely true to a vertical cut regardless of lateral tore sion. In this head member is formed the saw back receiving slot 43 which communicates with the saw blade receiving slot H carried vertically down through both the stem 36 of the member 35 and the cylindrical portion of the fixed guide 3% in the manner illustrated in Fig. a and serving the obvious purpose. On one side of this saw blade receiving slot as carried through the fixed guide is slidably positioned the gage 45 which is adapted to determine the depth of the saw cut by means of an annular portion 46 which is bent to engage with the stem 36 and, upon downward movement of the member 35, with the head thereof in order to check such movement, the gage member being secured by an adjusting screw 47 to the proper height.

The method of mounting these fixed guides 3-l upon the lever 20 is also disclosed in Fig. l consisting of a reduced portion 4L8 of the central cylindrical body which is accommodated in suitable apertures formed in the lever 20 respectively adjacent the opposite ends and which also accommodates the stem 36 in order to permit such stem to slide through the lever 20, the lateral guides 39 being so spaced by their buttressed retaining guides as to be depressible below the lever 20 and upon either side thereof as is clearly illustrated in Fig. 3.

As a work holding feature there is adapted to be attached to each end of the table top 10 and offset from the leg pieces 11 as illustrated in Fig. 1, the brackets 49 which are formed with T-slots 50 in which there is positioned a T-shaped slide 51 hearing at the forward extremity thereof an upwardly projecting pin 52 the distance between which and the back 12 of the table may be thus adjusted in order to accommodate work of various widths therebetween. In the detail illustration of Fig. 5 there is to be noted the adjustable means maintaining the slide 51 in any desired fixed position, such means including a washer 53 seated in a lateral aperture 54: formed in the bracket 49 in order to contact with the adjacent side of the slide, such washer being secured in place by means of a screw 55 projecting substantially through the bracket a9 and through a cylindrical recess 56 in which is accommodated the expansible coiled spring 57 acting against the innermost wall of such recess and outwardly against the washer plate 53. It will be obvious that a tightening of this screw will create a frictional locking force between the stationary washer and the slide, while a slight untwisting of the screw, a half revolution or more will permit the spring to dislodge the washer from the mentioned fricthe spirit of the invention tional contact in order that the slide may be again transversely adjusted.

The triangular cut out portion or groove 1% which may derive a certain utility from the fact that cuts of are so often made, may be bridged by a suitable gap plate 58 of correct size as to bring the surface of this cut out portion flush with the upper surface of the table top 10. Screws 59 are made use of to maintain this gap plate in its desired position when the longitudinal edges of the work to be out are in contact with the back 12.

Aside from the gap plate which is preferably of wood in order to protect the saw teeth upon completing a cut, it is obvious that the remaining elements of this miter box or table may be readily constructed from a suitable metal if it is so desired and also that means have been disclosed in the foregoing whereby the previously presented objects are capable of being attained so that the invention may therefore be claimed as possessing the advantages and desirability set forth in such objects.

While in the foregoing however, there has thus been illustrated in the drawings and described in the specification, such combination and arrangement of elements as constitute the preferred embodiment of this in-- vention, it is desired to emphasize the fact that such minor changes in the matters of proportion and degree may be made in later adaptations of this device as shall not alter as defined in the appended claims.

What is claimed is 1. In a. niitering table of the class described, a top, supporting means for said top, a lever pivoted to said top, fixed guiding members having extended side portions mounted upon said lever and provided with guide grooves in said extended side portions, said fixed guide members having longitudinal bores and slots coimnunicating with said bores to accommodate a saw, movable stems mounted in said guide members and adapted for reciprocating movement in said longitudinal bores, said stems having slots connnunicating with the slots of the fixed guide members, heads mounted upon said stems and provided with slots connecting with the upper ends of the slots of said stems and adapted to receive the back of a saw, said heads having extended side portions, and lateral guide members depending from said side portions for movement in the first-mentioned grooves of said fixed guide members.

2. In a mitering table, the combination of a top, a horizontally swinging lever pivoted to the under side of the same and extending transversely beyond the front and rear edges thereof, a fixed vertical saw guiding member having a cylindrical bore, mounted 011 each end of said lever, each member having an exterior longitudinal groove in one side, a cylindrical saw guiding stem movable vertically in the bore of each fixed guiding member, alined slots in each fixed member and movable stem, and a finger depending from the upper end of said stem and engaging the groove in the side of the fixed member to prevent rotation of said stem and maintain said slots in alinement.

In testimony whereof I aflix in presence of two witnesses.
